PINCKNEY PRUE BENSON, OF LITTLE ROCK, ARKANSAS.

PLOW.

SPECIFICATION forming part of Letters Patent No. 351,420, dated October26, 1886.

Application filed May 1, 1886. Serial No. 200,816.

To aZZ whom it may concern:

Be it known that 1, IINcKNEY PRITE BEN- SON, of Little Rock, in thecounty of Pulaski and State of Arkansas, have invented certain new anduseful Improvements in Flows; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to an improvement in plows.

The object is to provide a plow in which the depth of out and rake ofhandles may be readily determined, and in which the plowblade may beadjusted up and down the standard.

A further object is to provide a plow-beam of improved construction, andto provide an extended heel for the standard, to make the plow-blade runsmoothly and steadily.

IVith these ends in view my invention consists in certain features ofconstruction and combinations of parts, as will be hereinafterdescribed, and pointed out in the claim.

In the accompanying drawings, Figure 1 is a view of the plow inperspective, and Fig. 2 is aplan view.

A represents the plow-beam. It consists of a single bar bifurcated atits rear end, and terminating at its forward end in a hook, a, for theattachment of the whiffletree or other draftconnecting device. Betweenthe branches 0, of the rear end of the beam the plow-standard B ispivotally secured, preferably by means of a bolt, 11, which bolt alsoextends through the lower ends of the handle-braces O. The standard Bconsists of a fiat bar slightly curved edgewise, and provided at itslower end with an elongated heel, D, extending rearwardly from the footof the standard and flush with the bottom thereof. The standard B ispreferably formed of a single bar split into two branches, 1), a shortdistance below the plowbeam, and the heel D is welded or bolted betweenthe lower ends of the branches; but the standard might be cast integralwith the heel, or the heel might be bifurcated to receive the lower endof the standard and welded or bolted thereto, or the heel might becrushed into the lower end of the standard and welded (No model.)

thereto. Above the heel D the standard is provided with an elongatedslot, 1?, extending through from the front to the rear edge, and theplow-blade E is secured to the front of the standard by means of one ormore, preferably two, draw-bolts, c, which extend through the slotd. Byloosening the nuts on the bolts 6 the plow-blade E may be shifted up ordown 011 the standard, and locked in the desired adjustment bytightening the said nuts, thus causing the blade to out deeper orshallower, and compensating for any wear which the lower end of theblade may have suffered.

A curved brace, F, is secured at its upper end between the branches ofthe plow-beam in front of the standard, and extends through the standardabove the plow-blade. The said curved brace is screw-threaded, and isprovided with a pair of adjustingnuts, f, one in front of and one at therear of the standard, by means of which the standard may be locked inany desired forwardly and backwardly swinging adjustment, and the depthof furrow thereby determined.

The handles Gare bolted to the beam at such a distance forward of thestandard as may be found expedient to give them the desired rake, andare secured to the standardbraces 0, one to each brace, by draw-bolts g.A series of perforations, g, in the braces O render the handlesadjustable to the desired height, as is common in plows hithertoconstructed.

The jointer or colter H is secured to the plow-beam in any desiredvertical adjustment, or adjustment toward and away from theplowstandard, by means of the clip I.

I am aware that it is not broadly new to adjust a plow-standard by abrace leading from the beam thereto, and that plow or cultivator bladeshave commonly been secured to the fronts of standards, and thatplow-handles and colters have been secured to plow-beams in such amanner as to be locked in different adjustments; but I am not aware thata plow; possessing the features particularly set forth above hashitherto been in use or known.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

- In ap1ow,the combinatiomwithaplow-beam specification in the presenceof two subscribbifuroated at its rear end, of the p1ow-standingwitnesses. and pivotally secured between the branches T of said beam,the curved brace pivoted to the PINCKNEY PRUE BEL 5 beam, and theheel-piece secured to the stand- Witnesses:
